Title: ST-20 Tube Sanding Block 3D model

Description: This is a 3D model of Estes ST-20 Tube Sanding Block. It is used for sanding ST-20 sized rocket tubes after filling the tube rings or priming, allowing you to achieve a smooth and consistent finish with ease. No fancy clamps to hold the paper. Just drape your sandpaper over the tool, and hold with your hand while you sand. This does a great job of creating an even sanding surface, rather than using any kind of flat block.
